Enter only the subdomain of the address you want to use for your Unbounce custom domain

For example, if you picked "promos.mysite.com" as your address, enter "promos"

Or, if you're using a root domain such as "www.mysite.com" then you'll want to enter "www"

Select CNAME from the Type dropdown

Enter "unbouncepages.com" as the Points To value

Click Add Record

If you get an error adding your CNAME, there may be an A Record set up for your subdomain (sometimes, setting up a new subdomain will automatically create an A Record in BlueHost). To solve this just delete the A Record from the DNS Zone Editor, then add your CNAME.

For more information, you can access BlueHost's support documentation:

CNAMEs can take up to 48 hours to propagate. Once it's ready, you can ensure your pages are published where you want by making sure your custom domain is added to Unbounce, and double checking that your landing pages are using your custom domain.
